v1.0.3

Added

• Added automated GitHub Actions release workflow (.github/workflows/release.yml) triggered by stable vX.Y.Z tags.
• Added release validation and notes extraction scripts: scripts/verify-release-tag.mjs and scripts/changelog-release-notes.mjs.

Changed

• Updated release process to use trusted publishing (npm publish --provenance --access public) from CI instead of manual local publishing.
• Added canonical npm release scripts (release:verify-tag, release:notes, release:gate) to package.json.

Fixed

• None.
